Stasys also has gained international recognition for his book illustrations and masterful posters, which often feature dreamlike imagery and deeply expressive figures.

Eidrigevičius is active in various artistic fields, including painting (pastel, oil, tempera), drawing, bookplates, book illustration, studio graphics, photography, installation art, sculpture, and scenography.

"For Polish art, the Lithuanian Stasys is what the Spanish Picasso, the Italian Modigliani, or the Russian Jews, Chagall, Zadkine and Soutine were for the Paris school."

Eidrigevičius started his career as children's book illustrator, quickly gaining recognition for his unique approach to visual storytelling.

During this period, Eidrigevičius also gained recognition for his ex libris prints (bookplates), which showcased his meticulous detail and imaginative compositions.

His masks and face-themed artworks, which he has explored in paintings, posters, and performances, reflect an ongoing inquiry into the nature of human expression and perception.

Although Eidrigevičius has made significant contributions to contemporary art, he is still awaiting broader international recognition, even though he is one of the most acclaimed artists in Eastern Europe.

He is regularly invited to participate in international art exhibitions, biennales, and jury panels, while also sharing his expertise with students worldwide.
